The pandemic is putting us under strain, and under strain there is less energy to sustain a false pretense. The husband showed his true colors. He already made vows to his wife when he was married. How can he now resort to vows again? This marriage is shattered by what he did. You are just trying to be hopeful when there is no hope. Hope to put the marriage back together again? Just like what it was---before he broke it? He would break it again. Who would want to go through a second experience?

Now, if he were to approach his wife in great contrition, remorse, and repentance, seeking remediation, and pleading for forgiveness, charity, and forbearance, that might be a basis for hope. But nothing less.
